Answer: SECOND OPTION
Step-by-step explanation:
Given the following equation:
![x^2-36=5x](https://tex.z-dn.net/?f=x%5E2-36%3D5x)
You can follow these steps in order to find the values of "x" that makes the equation true:
1. Subtract
from both sides of the equation:
![x^2-36-5x=5x-5x\\\\x^2-5x-36=0](https://tex.z-dn.net/?f=x%5E2-36-5x%3D5x-5x%5C%5C%5C%5Cx%5E2-5x-36%3D0)
2. Factor the equation. Find two numbers whose sum be -5 and whose product be -36. These are 4 and -9:
![(x+4)(x-9)=0](https://tex.z-dn.net/?f=%28x%2B4%29%28x-9%29%3D0)
Then you get:
![x_1=-4\\\\x_2=9](https://tex.z-dn.net/?f=x_1%3D-4%5C%5C%5C%5Cx_2%3D9)
Checking:
![(-4)^2-36=5(-4)\\\\-20=-20](https://tex.z-dn.net/?f=%28-4%29%5E2-36%3D5%28-4%29%5C%5C%5C%5C-20%3D-20)

TRUE
Hey there!
Answer-
See Below.
Step by step explanation-
Let the number of 50 paise coins be x, then the number of 25 paise coins will be 4x.
The value of 50 paise coins is 50x paise and the value of 25 paise coins be 25(4x)=100x paise.
According to the giving condition,
![50x + 100x = 6000](https://tex.z-dn.net/?f=50x%20%2B%20100x%20%3D%206000)
![= > x = \frac{6000}{150} = 40](https://tex.z-dn.net/?f=%3D%20%20%3E%20x%20%3D%20%20%5Cfrac%7B6000%7D%7B150%7D%20%20%3D%2040)
∴The number of 50 paise coins is 40 and number of 25 paise coins is 4x=4(40)=160.
Answer:
57.2°
Step-by-step explanation:
sin 26° = x/19
x = 8.329051789
(7 / 8.329051789)
So 4's facts
we know that 4 times 2=8 and the associative property of multiplication says
a(bc)=(ab)c
so 7(8) (means 7 times 8) means 7((4)(2)) and associative say we can group them and say (7)(4)(2) so (4)((7)(2)) or 4(14) and 4 times 14=56
7 times 8=56
